    摘要: A speed control system for a passenger vehicle provides a predetermined brake mode operation to control the vehicle speed when the vehicle speed plus a determined speed offset responsive to a calculated effort request signal is equal to or greater than a desired program stop speed, and then compares the calculated effort request signal with a predetermined value of the effort request signal to control the vehicle speed in response to the calculated effort request signal.

    摘要: An electric power vehicle includes a propulsion system connected to a direct current (DC) source via a supply line. The propulsion system converts the DC supplied via the supply line to an AC electrical power to operate an AC motor at a desired level. An electromagnetic interference detection system for the vehicle includes an EMI processor connected to a current transducer and the propulsion system. The transducer detects AC signals appearing on the supply line and provides an output to the EMI processor. The EMI processor determines the frequency, amplitude and duration of the detected AC signals and causes the propulsion system to adjust the AC electrical power supplied to the motor as a function thereof.

    摘要: A passenger vehicle speed control apparatus and method are operative with a track providing an input speed command having ONEs and ZEROs information components. At least two programmed microprocessors operate with the vehicle and redundantly decode the ONEs and ZEROs input speed command signal components through operation of a fixed frequency filter for each of a plurality of frequency pairs and a variable frequency filter tuned to the frequency of the fixed filter having the highest amplitude signal component for determining a speed command signal to control the movement speed of the vehicle.
